Answer:
17.5
Step-by-step explanation:
The following data were obtained from the question:
Angle R = 105°
Side R = r
Side S = 15
Side T = 6
The value of r can be obtained by using cosine rule formula as shown below:
inding sides:
r² = s²+ t² – 2st cos(R)
r² = 15² + 6² – 2 × 15 × 6 × cos105°
r² = 225 + 36 – 180 × cos105°
r² = 261 + 46.587
r² = 307.587
Take the square root of both side
r = √307.587
r = 17.5
Therefore, the value of r is 17.5
12 squared plus 5 squared equals C squared
144+25=169
Square root of 169 is the answer
C= 13 mi

The answer is 0.5833333333
Answer:
Step-by-step explanation:
Divide R by 312 (R on top of the fraction, 312 on bottom) and set it equal to 93.
